SHO CKER.

Application filed August 20, 1919. Serial No. 318,738.

top of the shock and around to it normal position, effecting a complete revolution during the cycle. This revolution of the pan is eli'ected by ground engaging treads which, when the pan is filled, are lowered into ground engagement so that a dumping operation is effected directly by ground contact and without the use of gears or similar transmission connections.

The invention consists essentially in the arrangement and construction of parts as hereinafter more particularly explained.

In the drawings:

Figure 1 is a side elevation of my shocker device showing the parts in normal position in full lines and in intermediate position in dotted lines;

Fig. 2 is a similar view to Fig. 1, showing the parts, in the position they assume when the shock is upended in full lines and in the returning position in dotted lines;

Fig. 3 is a plan view of the shocker device showing its connection to the binder;

Fig. 1- is an end elevation of the shocker device and its connection to the binder frame.

Figs. 5, 6 7, 8 and 9 are diagrammatic views showing the successive positions assumed by the pan in discharging the shock to the ground and Fig. 10 is a perspective view of the forward end of the sheaf receiver and associated threads.

In the drawings, like characters of reference indicate corresponding parts in the varioug figures.

1 represents the frame of the machine, which comprises two side rails 2 and 3 and a cross connecting bar 4, making the main portions of the frame U shape. The forward right hand side of the machine is supported by a wheel and the rear right side by a swivel castor wheel 6. The left side of the frame 1, formed by the bar 2 conflicted to the binder by a bracket 7 of suitable construction.

8 indicates the main wheel of the binder, and 9 the binder deck indicated by dotted lines in Fig. 10 and 11 indicate pivot bolts upon which are swingingly mounted, at one end, bars 12 and 13.

The bars 12 and 13 are each preferably formed by two bar members l2 and 12 and 13 and 13, through which the pivot bolts extend and are separated by suitable spacers let and 15, as shown in Fig. 3. It will thus be seen that the swinging bars 12 and 13 are swung at each side of the frame 1 and pivoted near the forward end thereof, the rear end being free to swing toward and from the ground. This construction forms in effect a pivoted inner frame which serves as a vertical swinging support for the pan or sheaf receiver presently to be de scribed.

By reason of the bars 12 and 13 comprising bar members which are separated by spacers, each bar will be provided with elongated slots 16 and 17 extending longitudinally of the bars and in parallel relation to the side bars or rails of the main frame.- The pivoted bar members, which comprise in effect the swinginginner frame, are normally held in raised position by means of triggers 18 and 19, each provided with a ratchet shaped notch 1S on its forward face, as indicated in dotted lines in Figs. 1 and 2. The upper ends of the triggers are pivot ally supported upon bolts 20 and 21 extending inwardly from the side rails 2 and 3 0f the main frame, the lower ends of the triggers being free to swing fore and aft. The trigger depend downwardly through the slot openings 16 and 17 near the rear or free ends of the pivoted bars 12 and 13 comprising the swinging frame. and the triggers are actuated by means of trigger release arms 22 and 23 pivoted at the rear end of the main frame intermediate of their length upon pivot bolts 2 1 and 25 inwardly extending from the rear ends of the side rails 2 and 3 of the main frame.

The upper ends of the release arms 22 and 23 are united by a cross rod 26 elevated above the main frame, which causes them to swing in unison, and wnich cross rod is provided p a bar 27 extending rearem in proximity to the driw wardly th n ti U till

cr's seat on the binder and in convenient relation to be operated manually by the driver. The lower ends ot the arms 22 and .313 are connected by links 28 and 29 to the lower ends ot the trigger hars 1&3 and it), so that a "forward thrust ot the cross rod will result in a retraction ot the two trigger bars. Each pivoted side bar 12 and 153 is provided with a roller 3t) which normally rests within the notch 18* ot' the 'nroximate trigger bar 18, so that a rearward retraction thereof will release the forwardly pivoted bars 12 and 13 and allow the re ends to fall. This releasing action is cted against the tension ot' spring 31 which connect the trigger release arms iii and 23 to the proximate side rails of the main frame.

The bars 12 and 13 which comprise the swinging inner frame are provided with inwardly extended stub axles located near the renter thereof, which .rtuh axles atlord trunnions for the mountin ot the sheaf receiver ti -lwhieh supported within a "frame or cradle consisting of upper rails 35 and lower rails 35" with cross straps 35 connecting with the sheaf receiver. The cradle is hung from the stub axles 3; and 33, as host indicated in Fig.

i no sheaf receiver is troughshaped and tapered t'rom the front to the rear and also from the top to the bottom and is open at both ends, so that when in its normal or receiving: position it will receive the sheaves butt-end forward and in longitudinal relation to the machine.

A revolution of the sheaf receiver is effected through the action of arc-shaped tire members 35 and $36 rigidly secured to the frame or cradle, so that the rotation of the tire members by contact with the ground will ellect a complete revolution of the sheaf receiver mounted upon its axles or trunnions. The arc-shaped tire members are lmsitioned in generally eccentric arrangement to the axis ot' the sheaf receiver. and the major radial dimens on of the tire members is in a plane transverse to the plane oi the open side of the sheaf riia'civcr; that to say, the tread portions of the tire members, at a point in immediate opposition to the open side ol the sheat receiver, will he more dis tantlv located from the axis of movement than at our other point, so that in thc revolution of the she-a t receiver the around contact ot the tire members will lift the axis of the shcal' receiver to its highest point when the shoal receiver is in overturned position and at the time when the shca l' receiver is somerstrutting; forward to clear the deposited shock. The tire members 83 and 36 are provided with tooth projections or spuds 37 or other snitahlc means for grip iingr the ground when the tires are brought into contact therewith.

The sheet receiver is provided at its rear end with stop projections 37 and 38 which engage with the iliwardl y projecting ends oil? the stud shafts ill and 251 which serve to limit the upwardly swinging return movement of the sheaf receiver a li er it is brought, back to normal position. 'lhe relation of the stop projections 37 and 38 and the studs 24: and is such that when the axis of revolution of the pan is elevated, as in the sheat receiving position shown in Fig. 1, the stop projections will slightly engage the under side of the stud shafts, but when the notched triggers are ithdra'wn and the loaded sheai' receiver is dropped to the position indicated in dotted lines, the stop projections will he swung" forward sutliciently to clear the studs on the upward rotating movement of the rear end of the pan. That is to say, the weight of the grain within the sheaf receiver will cause the pan to drop and pitch slightly forward until the tire members engage the ground, and this movement is sutiicient to enable the stop members to clear one another. On the return movement, however, the line]. momentum of the pan, alter the discharge of its load, will he suiticicnt to swing; the rear end of the pan upwardly until the stop members engage one another, in which position the latch trigger will engage to prevent the inner pivoted frame from falling back into ground contact while the preponderance of weight at the enlarged :i'orward end of the pan will maintain the stop members in engagement.

The side rails 12 and 1;} have secured thereto cams 35$ and it) provided with inwardly opening opposing camways ell which tarnish endless cam contact faces 42 and 4:3, as indicated in section at the upper portion o't Fig. 3. it indicates a rocking cross rod extending between and pivoted throinrh companion bars and eltt, each bar being cured at its inner end to the proximate cradle rail 35 adjacent; the rim of the sheaf receiver and cxtenclin c in right angle relation awa therefrom toward the tire mcn'iher to which it is secured, which arrzmgremcnt furnishes a pivotal mountii'ie; tor the ends oil'? the cross rod, which rod extends across the open side of the sheaf. receiver at a point near the cnlarsml :t'orward or lnlttreceiving); end lhercot'. The ends ol the pivoted cross rod are provided with crank arms 4'? and iteach carrying a cam roller which extends into the :nljaccut caniwz'i g ll and alter-- natelv engages the cam surt'aces 1.2 and t as the sheaf receiver is o'vcrenrlcd to dis charge the shock. The cam surla cs l2 and iii are so shaped as to (titlt'lj with the cam rollers h) to exert a constant rearward pressure upon the shot-l; as the same is being! r l. charged by means of a spring; held arm fit) which is swung rearwardlv by the rotating: oi" the rod 4st as the sheaf receiver carried to the discharging position, which rearward pressure counteracts the tendency of the shock to topple forwardly when bu-tted on the ground.

In operation, the sheaves are discharged from the binder deck 9 into the upwardly opening receiver 3% with the butts extending forwardly, the receiver being tapered from front to rear in order to allow the butts to spread so as to give the shock a firm hold on the ground when upended. hen the required number of sheaves have been deposited in the receiver the push bar 27 is thrust forwardly by theoperator of the binder, thereby rocking the trigger release arms 22 and n3 upon their supporting stud shaft-s 24: and 25 in the direction of the arrow (see Fig. 1) against the tension of the springs 31. By this means, through the link bars 28 and 29, the trigger bars 18 and 19 are swung rearwardly, thereby carrying the notches 18* from beneath the rollers 30, which releases the rollers and allows the rear ends of the bars 12 and 13 comprising the inner swinging frame to swing downwardly on their forward pivots. The weight of the grain in the receiver, and the distribution of the weight, is such as to cause the forward end of the receiver and the corresponding portion of the tire memher to engage the ground, a indicated in dotted lines in Fig. 1. The continued ad vance of the shocker then causes the sheaf receiver to rotate with its pivot in the lowered position, in which position the stops at the rear end will clear the stud shafts 2i and 25 and the rotation will continue throughout the cycle. When the parts have reached the vertical position illustrated in full lines in Fig. 2 and Fig. 6, the shock will be butted on the ground, and the free end of the pressure arm will be drawn back into firm contact with the middle of the shock by the action of the rollers on the crank arms at"? with the corresponding cam surfaces. lVith the parts in this position, the

rod i l will bear against the base of the shock at a point slightly above the ground. This holds the shock steady while the sheaf receiver is moving from the position indicated in Fig. 6 to that shown in Fig. 7 which consitutes the critical point in the deposition of the shock on the ground. AL though the machine as a whole is forwardly advancing, the base portion of the receiver at its discharging end will swing backward ly with respect to the machine, and upwardly over the rear upper face of the depositec shock so as to substantially clear the shock at this point without appreciable interference, the shock meanwliile being steadied by the contact of the pressure arm 50 and the cross bar 44.

As the sheaf receiver continues its rotation to the position shown in Fig. 8, it will somersault over the deposited shock, and this action is facilitated by the configuration of those portions of the tire members which lie adjacent to the open side of the sheaf'receiver. These portions of the tire members, being outwardly bowed to a greater extent from the center of rotation than other portions of the tire member, will bodily lift the sheaf receiver when in its overturned position, thereby enabling it better to clear the deposited shock without tending "to upset the same.

7 The tire me ibers will continue their ongagement with the ground until the sheaf receiver has swung almostback to its normal position. at which point the termination of the tire members is reached and the ground contact ceases. However, at this point the pan will have acquired sufiicient rotative momentum to cause its rear or reduced end to swing on upwardly, which upswinging is facilitated by the disposition of the weights of the 3211 on opposite sides of its pivotal axis, and the momentum also lifts the free ends of the pivoted swinging inner frame bars 12 and 13 sufficiently to latch the same concurrently with the stop ping of the rear end of the pan by contact of the stop members. The cycle of operations is thus completed with the pan again in its receiving position with its open side upward.

It will be observed that ground contact of the tire members is continuous throughout the entire butting operation, so that means are afforded for positively carrying the pan completely over the shock in accurately timed relation to the advance of the machine, and at the same time, by providing tire members of the character indicated, the somersaulting movement of the pan can be accurately regulated to afford the necessary clearance between the pan and the deposited shock at all points during the cycle of operations. As a result of this arrangement, the only pressure which will be brought to bear upon the shock will 1e direct, by the pressure arm 50, against the middle of the shock, and it is desirable that the cams which control the movements of the pressure arm be configured to cause the free end of the pressure arm to travel rearwardly in an arcuate movement with suflicient speed to continue this contact at the middle portion of the shock until the same is firmly butted, and the tendency to overturn, caused by the forward momentum of the mass of grain, has been overcome. At the same time the contact of the cross rod or rock shaft 44 against the base of the shock will be relieved and compensated by the forward advance of the machine, so that the swinging movement of this rod will not have a tendency to trip under the base of the shock and thereby overturn. the same.
